Abstract
The utility model relates to an improved porous ceramic sheet for a gas burner, which is made of solid ceramic material such as cordierite. The porous ceramic sheet for a gas burner is characterized in that the shape of the cross section of a fire hole is a regular triangle; thus, the smaller area of a single fire hole and the proper hole opening percentage can be achieved via art manufacture; as for an infrared gas burner using manufactured gas, the backfire phenomenon can be overcome effectively and the combustion is can be complete; the heating performance of the gas burner is improved. The ceramic sheet is applicable to gas burners using the gas such as liquefied petroleum gas, natural gas, manufactured gas, etc.
Description
The utility model relates to the improvement of gas stove burner, especially to the improvement of porous ceramics piece in the household infrared ray gas kitchen ranges.
As everyone knows, since the household infrared ray gas kitchen ranges appears on the market, now accepted by consumers in general.Compare with the air suspended type kitchen range, it have energy-conservation, efficient, pollute less, advantage such as security performance is good, health is clean.Because infrared burner adopts a premix air burning mode, burning is carried out on its red-hot surface, porous ceramics piece surface temperature height, and burning velocity is fast, easily causes tempering phenomenon.When being mounted with when infrared radiation produced the utensil of strong reflection the easier generation of tempering phenomenon on the kitchen range.Especially when the source of the gas that uses during as artificial coal gas, generally all calorific value is low owing to artificial coal gas, and burning velocity is fast, and therefore, the tempering problem that solves the artificial coal gas infrared kitchen range becomes a big technical barrier of this gas kitchen ranges.
Solve the tempering phenomenon of infrared gas stove tool, following several method is generally arranged: (1) reduces primary air ratio, reduces total fire hole area, if but primary air reduces too much, causing incomplete combustion, and the carbon monoxide content in the flue gas is raise, then is worthless; (2) increase the distance in the combustion front and the bottom of a pan, this method will make the thermal efficiency reduce greatly, thereby also is worthless; (3) reduce each fire hole area, this is the better method of dealing with problems.But by in the past fire hole shape, reduce the restriction that each fire hole area is subjected to process for making, want the fire hole area that reaches required, garden shape fire hole is to be difficult to meet the requirements of.
The purpose of this utility model is by changing the shape of each fire hole, make the fire hole of this shape, burning to combustion gas has stronger inhibition drawing effect, and the appropriate and little porous ceramics piece of each fire hole area of the fire hole percent opening of producing on the technology, reach under the prerequisite that does not reduce the thermal efficiency, can overcome tempering phenomenon, the carbon monoxide content in the combustion product gases is not raise.
The utility model is realized as follows: the porous ceramics piece gross area is constant, and the cross section of each fire hole (1) becomes equilateral triangle by original garden hole shape, and each equilateral triangle fire hole area is not more than 1 square millimeter.In kitchen range are produced, can specifically determine each fire hole area according to the kind and the component of various places combustion gas, if artificial coal gas, each fire hole area then should be not more than 0.8 square millimeter.Because extrusion process, equilateral triangle fire hole (1) is by interfix mode arranged distribution.
Adopt the equilateral triangle fire hole, compare,,, make the triangle fire hole have stronger anti-tempering ability because position, three angles of triangle fire hole has occupied certain area when when single fire hole area is identical with hole, garden fire hole.Because the process characteristic of triangle fire hole is produced the less triangle fire hole of single fire hole area easily, reaches the tempering phenomenon that suppresses the infrared gas stove tool effectively.For using the fast artificial coal gas equilateral triangle porous ceramics piece of burning velocity, single fire hole area should be not more than 0.8 square millimeter.For the porous ceramics piece that uses liquefied petroleum gas or natural gas, its single fire hole area can amplify, and be not more than 1.1 square millimeters as single fire hole area, and the porous ceramics piece percent opening of triangle fire hole can reach 35%～65%.When the total surface area of pottery is constant, can obtain appropriate primary air for the infrared gas stove tool, promptly regulate primary air, reach appropriate primary air ratio: 1≤α≤1.3 by regulating percent opening (being the fire hole gross area).Like this, the utility model is made small fire hole area ceramics by adopting the triangle fire hole to reach, thereby suppresses tempering, and the anti-tempering ability of triangle fire hole itself is strong, and the means of this two aspect make kitchen range can overcome tempering phenomenon effectively, carbon monoxide content in the flue gas is low, and thermal efficiency height.
Because the porous ceramics piece wall of triangle fire hole is thin, for intensity and the life-span that guarantees potsherd, and brings into play the strong advantage of the anti-tempering ability of triangle fire hole potsherd effectively, potsherd is by hard ceramic manufacturings such as cordierite, aluminium titanates.
Advantage of the present utility model is calorific value low, and burning velocity is fast, and easily the artificial coal gas of tempering can more effectively overcome tempering phenomenon, and the carbon monoxide content in the flue gas is controlled in the very low scope, satisfies the requirement of standard, and thermal efficiency height.
Because the potsherd percent opening scope of this triangle fire hole is bigger, when using than large opening rate, also be applicable to liquefied petroleum kitchen range and natural gas kitchen range simultaneously, it is strong also to have anti-tempering ability, low, the thermal efficiency advantages of higher of harmful substance in the combustion product gases.
Below in conjunction with the description of the drawings, provide embodiment.
Fig. 1 is a longitudinal sectional view of the present utility model;
Fig. 2 is local fire hole lateral cross section of the present utility model and distribution map thereof.
Embodiment 1:
A kind of porous ceramics piece that uses artificial gas appliance is made with the cordierite raw material, and the cross section of its each fire hole 1 is an equilateral triangle, and is mutually inserted arranges on potsherd.
Embodiment 2:
With embodiment 1, be employed fuel be liquefied petroleum gas.
Embodiment 3:
With embodiment 1, be employed fuel be natural gas.
